XmListSetAddMode — A List function that sets add mode in the list "XmListSetAddMode" "List functions"

XmListSetAddMode allows applications control over  Add  Mode  in  the  extended  selection  model.   This
       function  ensures  that  the mode it sets is compatible with the selection policy (XmNselectionPolicy) of
       the widget. For example, it cannot put the widget into add mode when the value of  XmNselectionPolicy  is
       XmBROWSE_SELECT.

       widget    Specifies the ID of the List widget

       state     Specifies whether to activate or deactivate Add Mode.  If state is True, Add Mode is activated.
                 If state is False, Add Mode is deactivated.
